Listen to the beautiful vowels of Lou Monte singing Bella Notte. His consonants are so crisp and clear that they make his words sound beautiful and so understandable. Also, his vowels are pure and clean. He isn't fudging or altering his vowels at all, which also adds to the clean sound of the words.
He also has lovely breath control to manage the long phrases, the delicate turns and swoons he manages so effortlessly. He is not just sliding around on every whim with no direction or control. You can tell that he knows how he wants to sound and he makes that happen.
